Kohler magnum 18

Greetings, Just came aboard.



I'm working on a Kohler Magnum 18 hp. Problem with petrol getting into the crankcase. I cleaned up the carb, didn't install a kit. There was no shut off solenoid in the carb, only the float valve. Changed the oil.



Question would you suspect the carburetor or the fuel pump? Have you run into this problem with the magnum? I see that the fuel pump is like the old mechanical pumps on car engines.



Thanks Richard
